SPECIFICATION forming part of Letters Patent No. 738,704, dated September 8, 19.03.

Application filed January 1'7, 1903. Serial No. 139,388. (No model.)

To all whom it Magnan/Gern.'

Be it known that L'PHILLIP SEMI/IER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Mosaic, of which the following is a full, clear, and exact description, reference being` had tothe accom? having theilexible sheet cementedto thefacen of the tessera.; Fig; fis alike view showing` a modified form of flexible sheet, and Fig. 6 is a view showing the tesserze laid in the cement of the wall.

My invention consists in the manufacture and use of flexible sheets of mosaic, consisting of glass or other tesserze, in the manner hereinafter more fully described;

`I will now describe my invention, so that others skilled inthe art may manufacture and use the same.

The tesseree maybe of glass, tile, or other suitable material, and they may be formed in any suitable manner and by any, suitable means. I prefer, however, to employ `such means as will Vgive the tessera a regular outline on its face and an irregular or enlarged outline on its base. These 'tesserze are assorted and assembled face downward to pro? duce the desired mosaic pattern, and wheni so formed a temporary backing of paper or other suitable material is connected to the bases of the assembled tesserze, which forms an assembled flexible sheet of tiling, which is shown in Fig. l of the drawings, a representing -the tesserze and b representing the temporary sheet. This sheet of tiling is then 'is cemented to the faces of the tesseree. The paper backing b is then removed from the bases of the tesserse by pulling it olf, and the flexible sheet of tiling formed by the tesserae andthe facing of gauze is readyto be laid in the usual manner.

By the use of tesserae having irregular or enlarged edges at their bases a much more sei cure and permanent mosaic ifis secured, the

plaster or cement of the wall or floor setting over these enlarged and projecting edges. It is, however, difficult to assemble such tesserae base downward, owing to the irregular outlines of their bases. By my improved method I am enabled to assemble the tesserze face downward, forming them intoa iiexible sheet, and owing tothe sheet of gauze which is then secured to the face of the tesserae I am enabled to remove the paper or other mav `terial from the back of the tesserae, leaving the bases of the tesserae free and clean to be engaged by the cement of the wall, and yet I still retain the mosaic in the form of aflexible sheet ready for transportation and use.

After the sheet of mosaichas been embedded in the cement ofthe wall orfloor in the usual manner the facing of gauze is removed by moisture or other suitable means.

The advantages of my improvement will be appreciated by those skilled in the art.

Having thus describedmy invention, what lI claim, and desire to secure by Letters Pat- Vent, is i, y The method of forming mosaic tiling, consisting in assembling the tesserze face downward, cementing a temporary sheet to the bases ofthe tesserae,cementing a flexible sheet to the faces of the tesseree, removing the temporary sheet from the base of the tesserae, laying the mosaic, and then removing the `flexible sheet 5 substantially as described.

`In testimony whereof I have hereunto set my hand.

PIIILLIP SEMMER.
